Question

我在Glassfish上运行的JSF 2（maven）项目中使用Shiro。添加了所有相关的依赖项（shiro-ehcache-1.2.2.jar，ehcache-core-2.5.0）。我的项目编译并运行顺利但是只要我用@ViewScoped注释标记ManagedBean，我就会遇到这个令人恼火的ClassNotFound异常：

异常发生在shiro-ehcache类中，它说：“java.lang.ClassNotFoundException：void”我无法推断，哪个类或jar导致了问题。看来我的豆子之一不能序列化但是哪一个？我的问题是：

在这种情况下，我们怎样才能找到违规类？

编辑：我有一个使用sessioncoped的导航bean：

@ManagedBean
@SessionScoped
public class NavigationBean implements Serializable {
private static final long serialVersionUID = 2L;

@Inject
private transient Logger log;

private String page = "/subpages/admin_home.xhtml";

public NavigationBean() {
}

public String getPage() {
    return page;
}

public void setPage(String page) {
    this.page = page;

}


}

另一个sessioncoped bean：

@ManagedBean
@SessionScoped
public class SettingsBean implements Serializable {

private static final long serialVersionUID = 1L;

@Inject
private transient Logger log;

private static final Locale Turkish = new Locale("tr");
private static final Locale English = Locale.ENGLISH;
private Locale locale = FacesContext.getCurrentInstance().getViewRoot().getLocale();
private static final Map<String,Object> countries;
static {
        countries = new LinkedHashMap<String,Object>();
        countries.put("English", English); //label, value
        countries.put("Türkçe", Turkish);
}

/**
 * Creates a new instance of SettingsBean
 */
public SettingsBean() {
    System.out.print("Settings bean constructed");
}

@PostConstruct
public void init(){
    log.debug ("Settings bean initialized");
}

public Locale getLocale() {
    return locale;
} 

public String getLanguage() {
    String lang = locale.getLanguage();
    if (lang.equals("en_US")){lang="en";}
    else if (lang.equals("tr_tr")){lang="tr";}
    return lang;
}

public void setLanguage(String language) {
    locale = new Locale(language);
    FacesContext.getCurrentInstance().getViewRoot().setLocale(locale);

    //String Msg = Messages.getResourceBundleString("M","LanguageChanged");
    String Msg = Messages.getString("LanguageChanged");

    FacesMessage facesmsg = new FacesMessage(FacesMessage.SEVERITY_INFO, Msg, "");  
    FacesContext.getCurrentInstance().addMessage(null, facesmsg);
    log.debug(Msg + " : " + language);
}

public Map<String, Object> getCountriesInMap() {
        return countries;
}


//value change event listener
public void countryLocaleCodeChanged(ValueChangeEvent e){

    String newLocaleValue = e.getNewValue().toString();

    for (Map.Entry<String, Object> entry : countries.entrySet()) {

       if(entry.getValue().toString().equals(newLocaleValue)){
                            setLanguage(entry.getValue().toString());
      }
   }
}

}

Answer 1

您可以使用Jboss的tattle tale来内省项目的lib文件夹，并以图形方式映射出依赖关系树。使用此工具，您可以找到类的依赖项。下载并解压缩项目后，运行以下步骤以找出哪个类正在破坏：

从命令行运行tattletale jar。例如

java -jar -Xmx512m tattletale.jar   <the path with your libraries> <the destination folder where you want the generated reports to be stored>

在输出文件夹中，您将找到一个文件夹树和一个 index.html 文件。打开此文件，然后选择依赖于链接。
在依赖页面中，您将找到库中的所有类以及每个类的所有依赖项列表。一个简单的“查找”操作将告诉您哪个类缺少您突出显示的类

Answer 2

正如@mrembisz所指出的那样，我已经检查了我的视图目录bean。我正在将一个状态bean注入到我的viewscoped bean中，虽然它正在实现“Serializable”，但它的一个或多个属性可能不是可序列化的。所以我改变了

@Inject
MyBean MB;

到

@Inject
private transient MyBean MB;

我认为“java.lang.ClassNotFoundException：void”消失了......但是因为我一开始没有得到那个例外，所以它偶尔会被抛出。我现在得到：
